7-Color mIF Staining Plus Kit for Human Tissue, TSA
The tissue microenvironment contains a complex cellular composition. Different compositions can be detected and identified by multiplex immunofluorescence staining.
The 7-Color mIF Staining Kit is designed to utilize TSA technology to effectively detect 7 different antigens on human tissue or cell samples when paired with user-supplied Rabbit or Mouse primary antibodies.

Note
This reagent kit is for research use only. The activity of expired reagents may be reduced. Inadequate dewaxing can affect staining results. To prevent possible false negative or false positive results, positive and negative controls should be conducted simultaneously during the experiment.
Principle
This 7-Color mIF Staining Plus Kit employs tyrosine signal amplification (TSA) technology, which utilizes HRP labeled secondary antibodies to catalyze the fluorescein substrates to stably covalently bound and amplify the fluorescent signal to the antigen. The non-covalently bound antibodies are removed using the heat repair method, and a second round of incubation is performed with the next primary antibody and another fluorescent substrate, so that multiple labeling could be achieved.
